Patents by Buforn (post 1908)

Constantino de Buforn Jacas, Figuera’s partner, after the death of Figuera, filed 5 more patents (47706, 50216, 52968, 55411 and 57955) dealing with the same system than the 1908 patent.

Those patents were filed between 1910 and 1914 and all of them are exact copies, and an exact copy of the original 1908 patent by Figuera

The translation of the 5 patents is worthless because there are more than 100 pages and all of them repeat the same principle as the 1908 patent but with more literature. Here we present the pdf with the scanned document of those patents.

For a deep study here it is linked the translation of the last patent (patent no. 57955). Next we present a summary of the key features of the patent. It just give some more details than the 1908 in certain aspect of the arrangement of the electromagnets. We encourage firmly to read this patent 57955 summary for better understanding of some aspects of the 1908 patent.

The way to collect this current is so easy that it almost seems excused to explain it, because we will just have to interposed between each pair of electromagnets N and S, which we call inducers, another electromagnet, which we call induced, properly placed so that either both opposite sides of its core will be into hollows in the corresponding inducers and in contact with their respective cores, or either, being close the induced and inducer and in contact by their poles, but in no case it has to be any communication between the induced wire and the inducer wire.
….
If you want even greater production you can place the inducers and the induced one after the other forming a single series in the next way: you place first an electromagnet N, for example, next another electromagnet S, and between their poles and properly placed you put the corresponding induced, with this we will have formed a group of battery as explained before, but now (instead of forming as many identical groups to the first one as number of induced coils needed) you can place, following the last electromagnet S, another induced and, after this last induced you can place an inducer N, following this inducer by another induced, and then by another S, and so on until having placed all the inducers which form the series of electromagnet N and S.

With this we will have succeeded in using the two poles of all inducers except the first and the last one of which we will have only used one pole and, therefore we will have as many inducers as induced minus one, this is, if “m” is for example the number of inducers, then the number of induced will be “m – 1”, which determine a considerable increase in the production of the induced current with the same expenditure of force.

…
Another advantage is that in the sinus of the core of the induced electromagnets we can put another small size induced electromagnet with equal or greater core length than the large induced one. In these second group of induced an electric current will be produced, as in the first group of induced, and this produced current will be sufficient for the consumption in the continuous excitation of the machine, being completely free all the other current produced by the first induced electromagnets in order to use it in all purposes you want.
